Public safety agency responsible for more than 400,000 residents selects Exalt microwave systems forone of the country’s first LTE emergency communications networks

CAMPBELL, Calif.—

October 9, 2012—

Exalt Communications, Inc. today announced that ADCOM911is using Exalt microwave backhaul systems to build one of the country’s first wireless broadband publicsafety networks using LTE. Exalt ExploreAir radios will ultimately be used to backhaul real-time datarelated to the critical, bandwidth-intensive applications needed to better serve residents of Adams County,a primarily rural area east of Denver covering 1,200 square miles, where broadband access is limited ornon-existent.

ADCOM911 is a multi-jurisdictional public safety communications center that provides voice, data, anddispatch services to first-responders at four law enforcement agencies and nine fire/EMS agencies.ADCOM’s network infrastructure consists of a mix of legacy TDM and advanced IP technologies, withland mobile radio (LMR) sites utilizing TDMA to carry voice traffic. To support this hybrid architecture,ADCOM is using Exalt all-outdoor ExploreAir 11 GHz systems, taking advantage of their high throughput,small form factor, and native support for TDM and IP.

“There has been an explosion in the need for real-time data by emergency responders, as well as acorresponding increase in the number of data-intensive applications being developed,” said Walt Leslie,senior communications technician at ADCOM911. “Our goal is to extend the full desktop client ofcommunications services to emergency responders throughout Adams County, wherever they may be.Choosing Exalt systems has allowed us to quickly, cost-effectively, and securely extend our coveragearea while supporting critical applications in their native network formats.”

While ADCOM911 uses fiber links to backhaul data in dense metropolitan areas, the majority of AdamsCounty is rural and lacks broadband access. ADCOM911 needed a microwave solution that wouldreliably carry both TDM and IP traffic and asked its primary vendor, Raytheon, to recommend and provideequipment that could be used to build an advanced LTE network.

“LTE gives Adams County the core infrastructure needed going forward,” said TJ Kennedy, director ofpublic safety and security for Raytheon’s Network Centric Systems business. “We are committed toproviding a solution that meets both the current and future needs of first responders.”

“ADCOM911 is providing a valuable roadmap that can help guide other emergency communicationsorganizations as they develop advanced wireless networks,” said Pamela Valentine, vice president ofoutbound and channel marketing at Exalt. “And ADCOM911 continues to stay ahead of the curve. Theywere the first in the nation to implement a 700-MHz simulcast LMR system, and now, working withRaytheon, ADCOM911 has built one of the first public safety LTE mobile broadband networks using Exaltwireless backhaul links throughout Adams County. These types of innovative networks highlight thereliability, security, and speed-of-deployment that Exalt microwave systems offer.”
